If your eyes feel gritty, tired or sore by the end of most days, you’ve probably already tried artificial tears. For a lot of people that’s enough. For others, drops alone don’t quite hold the line, and that’s usually when punctal plugs for dry eyes come up in conversation. They’re a small, reversible way of keeping the tears you already have on the surface of your eye for longer, rather than constantly topping up from a bottle. The idea is almost deceptively simple, block the tiny drainage holes at the inner corner of your eyelids, and your natural tears, or your drops, stay put instead of draining away within minutes. This guide walks through what punctal plugs actually are, how the procedure works, what the evidence says about how well they perform, and what to expect if you’re considering them at Bilba Clinic.
What Are Punctal Plugs
Punctal plugs are tiny devices placed into the puncta, the small drainage openings at the inner corner of your eyelids. Each eye has two of these openings, one on the upper lid and one on the lower lid, and each is only about as wide as three human hairs. Normally, tears drain through the puncta into a duct that leads down into your nose, which is part of why your nose runs when you cry. A punctal plug sits inside one or both of these openings and slows or blocks that drainage, so tears stay on the surface of your eye rather than disappearing down the duct. It’s a bit like fitting a stopper into a sink so the water doesn’t drain away as fast. The plugs themselves are small enough that you won’t feel them once they’re in place, and they don’t sit anywhere near the surface of the eye itself, so they don’t interfere with blinking or vision.
Punctal Plugs for Eyes, Also Known as Lacrimal Plugs
You’ll sometimes see punctal plugs for eyes referred to by a different name entirely, lacrimal plugs. Lacrimal simply refers to anything to do with tears and the glands that produce them, so the two terms describe exactly the same device. Whichever name a clinician uses, the purpose is identical, to help your eyes hold onto moisture instead of losing it too quickly. It’s worth knowing both terms, since some clinics and research papers favour one over the other.
How They Help With Dry Eye Syndrome
Dry eye syndrome, sometimes called keratoconjunctivitis sicca, happens when there isn’t enough of the watery part of your tears to keep the surface of your eye properly lubricated. A healthy tear film also relies on an oily layer and a mucus layer working together, and when any part of that balance is off, eyes start to feel dry, gritty or tired. Blocking the drainage route means whatever tear production you do have gets more time to do its job, and any artificial tears you’re using stay in contact with your eye for longer too. For some people that extra time is enough to noticeably settle symptoms like burning, grittiness or blurred vision that comes and goes throughout the day.
What Causes Dry Eyes in the First Place
Dry eyes can develop for more than one reason, and it’s worth understanding roughly which camp you fall into before jumping to punctal plugs.
- Not enough tear production, often linked to age, certain medications or autoimmune conditions
- Meibomian gland dysfunction, where the oily layer that normally stops tears evaporating too fast doesn’t work properly
- Tear duct blockage or drainage that’s too efficient, meaning tears clear away before they’ve done their job
- Environmental factors like air conditioning, screen use, low humidity or smoking
Some underlying health conditions make dry eye more likely, including Sjögren’s syndrome and other autoimmune conditions, and certain everyday medications such as antihistamines, antidepressants and beta blockers can reduce tear production as a side effect. Most people start with artificial tears, and for mild to moderate dry eye that’s often all that’s needed. Punctal plugs tend to come into the conversation when drops alone aren’t holding symptoms steady, rather than as a first step.
Types of Punctal Plugs
Punctal plugs aren’t all the same. The two materials you’ll come across most are silicone and collagen, and the choice between them usually comes down to how long you and your clinician want the effect to last.
Silicone punctal plugs are firmer and designed to stay in place for months or longer, until they’re deliberately removed. Collagen plugs are softer and dissolve on their own, usually within a few weeks. A collagen vs silicone punctal plugs comparison often comes up early on, because collagen is frequently used first as a trial run, a way of checking whether blocking the drainage actually helps before committing to a longer-lasting silicone plug. There are also a couple of less common variants worth knowing about, medicated plugs that slowly release medication into the eye, and perforated plugs with a small hollow centre, which are sometimes used when tears already drain too slowly rather than too quickly.
Temporary vs Permanent Punctal Plugs
Nothing about punctal plugs has to be permanent unless you and your clinician decide it should be. Temporary vs permanent punctal plugs isn’t really an either-or choice, it’s more of a progression. Collagen plugs dissolve naturally. Silicone plugs stay put but can be removed at any point if they’re not helping or if your eyes start watering too much. Is punctal plug insertion permanent? Not by default. True permanent closure, done by cauterising the drainage opening shut, is only usually offered once temporary plugging has already shown it works well for you.
How Punctal Plug Insertion Works
Punctal plug insertion for dry eyes is done in clinic, as an outpatient procedure, and it’s quicker than most people expect. Your clinician will usually numb the eyelid with a topical anaesthetic and use a lubricant to help the plug slide into place. About three quarters of tear drainage happens through the lower opening, according to NHS guidance on dry eye syndrome, so that’s usually where a plug goes first. If your eyes are still dry after that, the upper opening can be plugged too. Punctal occlusion for dry eyes doesn’t involve any cutting or stitches, and most people are back to normal activities immediately afterwards. Many notice less dryness within a day or two, though for some it can take slightly longer to settle in.
Does Insertion Hurt
No, punctal plug insertion for dry eyes isn’t painful for most people. You might feel a small amount of pressure or a slight tug as the plug goes in, but the numbing drops mean you shouldn’t feel anything sharp. Any mild sensitivity afterwards usually settles within a day, and there’s no downtime, so you can drive yourself home and return to normal activities straight away.
Are Punctal Plugs Effective
Are punctal plugs effective is a fair question, and the honest answer is that the evidence is more mixed than a lot of marketing around this treatment suggests. Several studies over the years have reported improvement in the majority of patients, with success rates commonly above 70%. At the same time, a large review of 18 clinical trials involving over 700 participants found the evidence inconclusive overall, meaning it wasn’t clearly proven that punctal plugs improve dry eye symptoms more than no treatment at all, though some trials did show small improvements in tear film stability and how long tears stayed on the eye’s surface. In practice, this tends to mean punctal plugs work well for some people and make little noticeable difference for others, which is exactly why a proper assessment matters more than assuming they’ll fix every case of dry eye. Part of the difficulty in measuring effectiveness comes down to how different studies define improvement, some track symptom scores reported by patients, others measure the physical stability of the tear film, and results don’t always move together. That’s not a reason to dismiss punctal plugs, it’s simply a reason to treat any single statistic with a bit of caution and judge success by how your own eyes respond rather than by an average from a study population you weren’t part of.
Punctal Plugs vs Eye Drops
Punctal plugs vs eye drops isn’t really a competition, the two are usually used together rather than as alternatives. Eye drops add moisture, punctal plugs help you keep hold of it for longer, including whatever moisture is already in the drops you’re using. Many people who start with drops alone move on to plugs specifically because the drops weren’t lasting long enough between applications, rather than because drops had stopped working entirely.
Possible Side Effects and Risks
Punctal plugs are generally considered safe, but like any medical device they carry some possibility of side effects.
- Punctal plugs fall out, which is the most commonly reported issue, especially with plugs placed in the upper eyelid
- Punctal plugs itchy or irritated eyes, usually mild and often settling within the first few days
- Watery eyes, if the plug blocks drainage more than your eyes actually need
- Rarely, inflammation, displacement, or infection of the tear duct
Most side effects are minor and resolve either on their own or once the plug is removed or repositioned. A small number of people develop a growth called a pyogenic granuloma near the punctum, caused by irritation, or notice slight narrowing of the opening after a plug is taken out, both of which a clinician can usually manage without further intervention. If irritation or discomfort doesn’t settle after the first week or so, it’s worth getting it checked rather than waiting it out.
Living With Punctal Plugs Day to Day
Day to day, most people forget the plugs are even there. Can you cry with punctal plugs? Yes, and it’s a question we hear often. Crying simply means your tear production has temporarily outpaced what the plug allows to drain, so you might notice slightly more watering than someone without plugs, but it isn’t uncomfortable or a sign anything’s gone wrong. Swimming, wearing eye makeup and using contact lenses are all still possible with plugs in place, though your clinician may suggest a short settling-in period first, and it’s sensible to avoid rubbing your eyes, since that’s one of the more common ways a plug gets dislodged. If you wear eyeliner along the inner lid, it’s worth being a little more careful around the corner of the eye where the plug sits, though most people find no real change is needed to their usual makeup routine. Contact lens wearers sometimes notice their lenses feel slightly more comfortable once plugs are in, simply because there’s more moisture available to keep the lens surface wet through the day.
Punctal Plugs Price at Bilba Clinic
Punctal plugs price varies depending on the material used and whether one or both eyes are treated. As a general guide, our pricing page lists insertion of canalicular or punctal plugs from £600, with the exact figure depending on your assessment and how many plugs are needed. We’d always recommend checking current pricing directly rather than relying on a figure that might be out of date, since costs can shift over time as assessments and follow-up needs vary from person to person.
When to Consider Punctal Plugs
When are punctal plugs recommended is really a question your clinician answers after a proper assessment rather than something to self-diagnose from symptoms alone. They’re typically suggested when artificial tears haven’t been enough on their own, when dry eye symptoms are affecting daily life, or when you’re using drops so often that a more lasting solution starts to make sense. They can also be recommended alongside other treatments for oculoplastic eye surgery patients recovering from eyelid procedures, where temporary dryness is common during healing. If eyelid position itself seems to be contributing to your dry eyes, our guide to droopy eyelid causes covers a related pattern worth ruling out too. Punctal plugs generally aren’t the right first step for very mild, occasional dryness, or for eyes that are watery rather than dry, so an assessment helps confirm you’re solving the right problem before going ahead.

Frequently Asked Questions
Can Punctal Plugs Get Infected?
Can punctal plugs get infected is a fair concern, though a genuine infection is uncommon. Clinical trial data has linked punctal plugs with occasional inflammation or infection of the tear sac, alongside more common issues like watery eyes. If you notice redness, pain, swelling or discharge around the plug, get it checked promptly rather than waiting to see if it settles.
Can Punctal Plugs Be Removed?
Yes, can punctal plugs be removed is one of the easiest questions to answer with certainty. Silicone plugs can be taken out in a quick in-clinic appointment at any time, for any reason, whether that’s because they’re not helping, causing irritation, or you’ve simply changed your mind. Collagen plugs don’t need removing at all, since they dissolve naturally within a few weeks.
Are Punctal Plugs Worth It?
Are punctal plugs worth it depends heavily on how much drops alone have or haven’t been managing your symptoms. For people whose dry eyes respond well to the extra retained moisture, many describe it as a properly useful, low-effort addition to their routine. For others, the improvement is more modest. Given the mixed trial evidence, it’s often worth trying a temporary collagen plug first rather than committing straight to a permanent option.
What if Punctal Plugs Don’t Work?
What if punctal plugs don’t work is worth planning for before you start, precisely because they don’t help everyone. If symptoms haven’t improved after a few weeks, your clinician might suggest removing them and trying a different plug type, adjusting your drops, or exploring other causes of dry eye that plugs alone can’t address, such as meibomian gland dysfunction.
How Long Do Punctal Plugs Last?
How long do punctal plugs last depends entirely on the type. Collagen plugs typically dissolve within a few weeks, making them useful as a short trial. Silicone plugs are designed to stay in place for months or years unless deliberately removed, though some do fall out sooner than expected, especially when placed in the upper eyelid.
